Application filed May a, 1909. Serial No. 493,821

To all whom it may concern:

Be it known that I, THOMAS CLoUsToN, a citizen of the Dominion ofCanada, residing at Vancouver, in the Province of British Columbia,Canada, have invented a new and useful Improvement in Gas-Producers, ofwhich the following is a specification.

This invention relates to a gas producer for the generation of a heatingor power gas from waste products, such as wood refuse or the like, orother gas generating material, and my object has been to devise a simpleand efficient producer from which the volatile vapors may be withdrawnand condensed to recover the distillates as byproducts, and whichcontains within itself provision by which the generated gas may beexposed to sufi'icient heat to render itstable.

The invention is particularly described in the following specification,reference being made to the drawings by which it is accompanied, inwhich:

Figure 1 is a vertical longitudinal section, Fig. 2, a sectional plan onthe line A A and Fig. 3, a sectional plan on the line B B.

In these drawings 2 represents a generating chamber the form andproportions of which may be varied to suit the requirements of thematerial from which it is re quired to generate the gas. The lower partof this chamber 2 is separated from the ash pit 3 by a partition grate tof any desired construction as the same per 86, forms no part of myinvention, or the pit 3 made separated from the chamber 2 by a platefrom which project upward a series of twyers 5 through which air admixedwith a little moisture, admitted at 6, is delivered into the chamber 2.The moisture admitted with the air is evaporated to form steam as itpasses to the ash pit 3 and before delivery through the twyers.

- Projecting upward within the generating chamber is a gas collectingand delivery stand pipe 10 which may be protected if necessary withrefractory material, fire clay or the like. This stand pipe has a closedupper end, just below which are a series of inlet apertures 11 upwardlydirected slightly inward. To this stand pipe 10 is connected beneath thegrate 4 a pipe 13 through which the gas is withdrawn by suction andpasses through the necessary washers and scrubbers direct to the engine.

The pipe connection 13 may if found desirable expose an extended areawithin the ash pit as shown in Fig. 3, and may deliver through the airinlet 6, to heat the incoming air before delivery to the twyers anddispense with the necessity for a separate regenerator.

The upper part of the generating chamber 2 is directed conically inwardas at 7 to the charging aperture to which a continuous feed hopper maybe connected, and from the charging aperture an inner casing 8 projectsdownward to about the level of the base of the converging cone 7. Fromthe annular space between the converging cone 7 and the inner casing 8,a pipe 9 delivers the volatile vapors which collect there to acondenser.

In action, the chamber 2 is charged with the material from which it isdesired to generate the gas and is ignited, the charge being maintainedto the upper level of the inner casing 8. Incandescence is maintained inthe lower part 15 of the generator by the air delivered through thetwyers 5 from the ash pit or regenerating chamber 3, which air ispreheated and its moisture evaporated to form steam by contact with thepipe 13 through which the hot gases are passing as generated to thewashers and scrubbers, and by contact with that pipe where it passesthrough the air delivery 6 to the chamber 8.

The gases for use, for heating or power purposes, are drawn from whatmay be called the generating strata 16 adjacent to the outlets l1 andpass downward through the central tube 10 which being surrounded at 15by incandescent fuel is maintained at the necessary heat to render thegas fixed and stable. Above the generating strata 16, the material hasits moisture and volatile vapors driven off by the heat from the stratabeneath and these vapors collect in the annular space between theconverging cone 7 and its inner casing 8 and pass through the pipe 9, inwhich a slight vacuum may be maintained, to be condensed for therecovery of the distillates as byroducts. Any non-eondensable gases maye withdrawn from the condenser and returned to the combustion strata 15through a pipe 20 where they will become fixed by passage through theincandescent fuel and will be drawn through the stand pipe 10.

The downwardly projected casing 8, not only forms a space wherein thevolatile vapors will collect, but will also permit a slight vacuum to bemaintained in the upper part of the chamber 2, and these gases will partwith their sensible heat to partially dry out the material as it ischarged through 8 and before it comes under the influence of thedistilling temperature to which it is exposed below that level.

lVhat I claim is:

1. In a gas producer, the combination with a generating chamber having apartition grate toward the bottom and a charging inlet projected withinthe top, twyers upwardly projected through the partition grate anddelivering air into the generator, means for collecting the gasgenerated from fuel charged into the generating chamber and fordelivering the same through a passage exposed to theincandescent heattoward the lower part of the generating chamber.

2. In a gas producer, the combination with a generating chamber having apartition grate across the bottom and a charging inlet projected withinthe top, of means for delivering air from the space beneath thepartition grate through twyers upwardly projecting from the partition,means for collecting gas generated from about the midheight of thegenerating chamber and for delivering the same through a passage exposedto the heat of the incandescent fuel in the lower part of the samechamber, and means for delivering the hot gas so collected through apipe exposed to the incoming air in the space beneath the partitiongrate.

3. Ina gas producer, the combination with a generating chamber having apartition across the bottom separating it from an air chamber beneathand having a charging inlet projected within the top, twyers deliveringair from the air chamber beneath to within the generating chamber and acentral stand pipe extending toward the mid-height of the generatingchamber having apertures toward its upper end and a pipe connectedbeneath the partition said pipe exposing a heating surface to theincoming air, said partition having upwardly projected aperturedmembers.

4. In a gas producer, the combination with a generating chamber having apartition separating it toward the bottom from an air chamber beneathand having a charging inlet projected within the top means for heatingthe air in the air space beneath the partition and for delivering thesame through that partition means for collecting the generated gas fromapproximately the 1nid-height of the generating chamber and for passingit downward through the incandescent fuel in the lower part of thegenerating chamber, means for delivering volatile vapors collecting inthe space around the inwardly projected charging inlet and means fordelivering noncondensable gas toward the lower end of the generatingchamber.

.5. In a .gas producer having an internal chamber, a partitionseparating said chamber into an upper generating chamber and a lower airchamber, said partition having twyers for passing air from the airchamber into the generating chamber, a central standpipe extending tonear the mid-height of the generating chamber and having apertures nearits upper end, a suction pipe coiled in the air chamber and connectedwith said standpipe, an air inlet duct to said air chamber through whichsaid suction pipe projects whereby the incoming air by contact with suchsuction pipe will be heated.
